Popis: The authors discuss the effectiveness of an overhaul done on a 3000-m/sup 3/ blast furnace with previous design deficiencies. During the overhaul, the diameter of the reinforcement of the bottom was enlarged from 14,330 to 15,130 mm. Other changes included replacing the lining in the region of the joint between the hearth and bottom by a single block, lengthening and widening the main troughs, and increasing the thickness of the shell of the bustle pipe. During the overhaul the bustle pipe was lined with refractories ShLB-1.0 and KL-1.3 and two courses of MKV-72. The reconstruction made it possible to alter the operating parameters of the furnace. The authors aimed to minimize heat loss with the coolant water from the stack and top and to maximize the gas permeability of the stock. Productivity of the furnace in the post-overhaul period increased 5432 tons/day at a coke consumption of 483 kg/ton pig.
